MOTOR-VEHICLE.

Application tiled August 16, 1915.

To al? (wlw/1i it may concern.'

Be it, known that l. .\Lv.\x MACAULEY, a citizen of the United States, and resident ot' Detroit, 'avne county, State ot' Michigan, have invented certain neiv and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor vehicles and particularly to the motor and its control.

It is well known that hydrocarbon motors operate better vvhen vvarm than when cold and that a richer mixture is required vvhen the motor is cold than when it is Warm or in normal working condition. Therefore, when a water cooled hydrocarbon motor, such as is used on motor vehicles, is started it ordinarily takes some time to warm it up and various devices are in use t'or temporarily adjusting the carburetor to give a mixture richer than normal to better operate the motor while it is warming up. Devices are in use also for controlling the water circulation through the cylinder' jackets during the warming up process.

Tlie present invention contemplates combining the control of the Water system and the carbnreter and adapting the water system and the carbureter to suoli combination in a novel and eiiective manner, and the primary object ot' the invention therefore, is to provide suc-h novel conibination ot elements together with new and useful constructions of the individual elements that go to make up the combination.

This and other objects of the invention will appear t'rom the following description taken 'With the drawings which form a. part of this specification, and in which the figure is a side elevation of the front end of a motor vehicle embodying the invention.

p Referring to the drawings, 10 represents one of the side members of a frame of a motor vehicle.y upon which is suitably supported a motor 11. The motor shown is of the usual hydrocarbon type, having a surrounding Water jacket 12 and a Water ci'rcH-' lation system comprising a pump 13. a pipe 14; leading from the pump to the water jacket 1Q, a pipe 15 leading to a radiator 1G, and a pipe 17 leading back to the pump 13 through a valve chamber 1S. There is also a by-pass 19 arranged in the water circulation system and comprising a pipe lead- Specicaton of Letters Eatent.

ing from the pipe 15 adjacent the upper part of the radiator 16 to the valve chamber 18.

The valve chamber 1S contains a sliding valve '2O operated by rod 21 which it will be seen extends out through the bottom of the casing.- The upper part of the casing 18 is closed by a cap 22. It will be seen that the by-pass 19 connects with the valve casing 15 through a port 223 which is at a higher level or in a diil'erent zone from a port 24 which forms the inlet from the pipe 1T. Thus the valve 2O is adapted toclose one of said ports at a time or it may partly close both of them. lts upper position is determined by a stop Q5.

26 represents the carbureter of the motor, which carburetor is provided vvith suitable means t'or varying'the mixture, that is, for changing the proportion of air and gas. As shown. the auxiliary air intake 2T of the carbureter is provided with a puppet valve 2S which is spring closed as by the springs 29. Thus it will be seen that the tenslon of these springs determines the degree of open: ing ot said valve by the suetion of the motor, and thus determines the amount of air to be supplied tothe carbureter to mix with the gasolene which enters through the usual nozzle, not shotvn.

The valve QS may be adjusted, that is, the tension of its springs Q9 may be adjusted, to suit various motor and climatic Conditions b v a Wedge 30 which operates beneath the springs 29 and increases or decreases their tension as the case may be. When the tenl sion of the springs is increased the valve 28 opens with greater difficulty and the mixture supplied by the carbureter is rich, and When the Wedge 30 is drawn out and the tension on the springs thereby decreased, the mixture is rarer or contains a greater proportion of airs Suitably mounted upon the Vehicle is a steering column 31 upon which is a hand controlled device 32 comprising a hand Wheel 33 which operates a pinion 31 meshing with a rack bar 35, which bar is thus adapted-to be adjusted longitudinally and yieldingly held in adjusted position as by 'a 'spring paivl 36. This hand Controlled device is adapted to operate or adjust the valves 20 and 2S hereinabove referred to, and for this purpose it is connected as .by bell-crank 31 and rod 3S with a sectional rod 39, which forms an interconnection be- 2i) uml Thi:- u
